The construction versions include the element for preheated (cooling) fluid: eleptical bottom or cilindrical chamber; different angles of arrangement of the inlet-outlet sleeves to the tube – and intertube spaces, and the position of mounting: horizontal and vertical.

In the type – series are included heat exchangers with following heat exchanging surfaces: 1,0; 2,5; 3,2 and 12,5 m2.

For an exact determination of the necessary heat exchanger for each particular case, data are necessary for the type and flowrate of the heat exchanged fluids, and also the temperatures of the heat exchanger inlet and outlet.
